The ODLIS states a Directory is:

"A list of people, companies, institutions, organizations, etc., in alphabetical or classified order, providing contact information (names, addresses, phone/fax numbers, etc.) and other pertinent details (affiliations, conferences, publications, membership, etc.) in brief format, often published serially (example: American Library Directory). In most libraries, current directories are shelved in ready reference or in the reference stacks."

*A sampling of directories is displayed on the Directory List page.
